Last week I debugged a Node issue where under some conditions, fork() failure could result in some file descriptors being closed, leading shortly to bedlam. In the best cases, the program would immediately crash, but often it would just do the wrong thing. This happens a lot, of course, and in many ways it's worse than a crash because you have no core dump nor even a stack trace to go on.

This is part of a series of blog posts on cloud security. Carlos Cardenas is a security expert who came to Joyent from The Institute for Cyber Security ICS at the University of Texas, San Antonio. While at ICS, Carlos worked under Ravi Sandhu, PhD, one of the leading security experts in the world.

In Part 1 of this webinar series Joyent's lead Manta architect, Mark Cavage, provides an introduction to, and explores the motivations for building Manta. Mark also provides insight into its underlying architectural features and reveals top use cases.
